Convert petawatt to joule/hour
Please provide values below to convert petawatt [PW] to joule/hour [J/h], or Convert joule/hour to petawatt.
1 PW = 3.6000e+18 J/h. To convert petawatt to joule/hour, multiply the value by 3.6000e+18; to go the other way, divide by it (1 J/h = 2.7778e-19 PW). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 PW = 3.6000e+18 J/h
- 1 J/h = 2.7778e-19 PW
- 10 PW = 3.6000e+19 J/h
- 100 PW = 3.6000e+20 J/h
How to Convert Petawatt to Joule/hour
1 PW = 3.5999971200023e+18 J/h
Example: convert 15 PW to J/h:
15 PW = 15 × 3.5999971200023e+18 J/h = 5.39999568000346e+19 J/h

Petawatt
A petawatt (PW) is a unit of power equal to 10^15 watts, used to measure extremely high power levels.
History/Origin
The petawatt was introduced in the 1980s as part of the SI prefixes to describe ultra-high power outputs, particularly in laser physics and astrophysics research.
Current Use
Petawatts are primarily used in scientific research involving high-intensity lasers, astrophysics, and nuclear physics to quantify extremely large power outputs.
Joule/hour
A joule per hour (J/h) is a unit of power representing the amount of energy (in joules) transferred or converted per hour.
History/Origin
The joule per hour has been used as a measure of power in various scientific and engineering contexts, especially where energy transfer rates are expressed over longer periods. It is derived from the SI unit of energy, the joule, divided by time in hours.
Current Use
Joule per hour is occasionally used in fields like heating, energy consumption, and industrial processes to quantify power over extended durations, though it is less common than watts for standard power measurements.
